I’m going to assume you’re not a troll.

What separates a good DJ from a great DJ?
[/quote]It depends on the type of DJ. In general, how good of a party they throw. To some, that’s mostly based on theatrics. To others, it’s about the quality of the music. There is no dividing line between good and great…it’s a continuum. Just like everything else.

Do all the great DJs (Aoki, Guetta, Skrillex, etc…) produce their own beats?
[/quote]The answer to your question is no, not all great DJs produce their own beats. Most of them do. When dance music started, it was because they heard something happening and didn’t want to wait around for other people to make the music they wanted to rock parties with…so they made it themselves. Now, it can still be that motive, but it’s also commonly a marketing tactic.
As for your list of awesome DJs, I’ve seen all of them live, some more than once. I won’t say anything to diminish their success: I wish I rocked crowds that big and got paid that much and got to travel and tour and spend all my time in studios or booths or planes having fun. But they are not my idols. The fact that they seem to be yours makes some of your questions make more sense.

Is mixing just putting in a CD and editing it real time?
[/quote]Basically, the act of DJing is making a mixtape for a party while the party is happening. The advantage is that the DJ can both lead and follow the partiers, so the music always fits. Exactly what that entails depends a lot on the era, the DJ, the music, the crowd, and a lot of other things. It started with just playing tracks and still follows that model most of the time…it can go as far as producing a track live, though that’s much more rare.

Are all songs made by DJs mixes? do they produce 2 songs and just mix them?
[/quote]DJing and Production are separate issues.
If your idols are Aoki, Guetta, and Skrillex, there isn’t a point.
